Below is a brief summary of our biggest achievements
A Well Characterised New BioBrick
The focal point of our wetlab work was the construction and characterisation of a new BioBrick [http://partsregistry.org/Part:BBa_K381001 BBa_K381001]. This part is a composite of two pre-existing BioBricks, with details of its design available here.
As shown in graph 1, we mapped its behaviour across the range where it was known to be most sensitive, further details of which can be found here.
We're proud of this part, and hope it will be useful to other teams in the future.
Elegant Solution to Signal Calibration
As well as making our BioBrick, we also worked further to develop a product that would actually function. As part of this we altered the traditional signal detection method of measuring output to remove the problem of misleading figures. Our new method of instead detecting the ratio of two outputs removes difficulties in distinguishing between large signals due to high Nitrate levels and those due simply to large colonies.
As is evident in graph 2, we well characterised this method and found it to work well, particularly within the range relevant to our project. Our results were even good enough to allow the construction of a formula linking signals detected to levels in the soil.

Novel Use of Cell Encapsulation
In what we believe is a first in iGEM, we used technology to both allow safe use of our E. coli in the public and environment dramatically improve signal detection.
Our Bead encapsulation method ensures a stronger signal that can actually be detected by our end user (farmers) without high tech equipment. It also reduces the risk of our bacteria escaping unchecked in the environment, and assisted in our human practices side of the project; making our product more appealing to the public.

Characterising A Pre-Existing BioBrick
As well as developing our own BioBrick, we also worked to better characterise one already in the parts registry [http://partsregistry.org/Part:BBa_K216005| BBa_K216005]. Graph 3 shows just one of many Miller assays we conducted to analyse its performance, more of which can be found here.
